there are 2 answers. You need to solve two different equations. |dw:1435066793729:dw|
ok. can you solve the equations above?
i cant @peachpi
ok. let's start with the left one. There's a 10 that's subtracted. How can you cancel it out (aka move it to the other side of the equation)?
add ten with 26 @peachpi
right. so what will the equation be after that step?
right, so now you need to cancel the 2 to find your x
divide 36 with the 2 @peachpi
ok @peachpi the answer is 18
correct! now follow the same steps to solve the right equation
same steps you used before. Add 10 to -26 then divide by 2
divide both @peachpi
divide both sides AFTER you add the 10 to both sides
this situation is a highly chance of you becoming depressed over one question of your propaganda !
divide both side by 2 @peachpi
i got 5 and 13 @peachpi
do you mean\[x-5=-13\]
I can't see what you're doing, so I'm not sure we're talking about the same equation. Can you use the draw tool to show me what you have?
When we solved the other equation we added 10 first. (see the one on the left.) Do the same thing for the equation on the right |dw:1435069181874:dw|
u get 18 @peachpi
yes. on the left equation we got 18. but there are 2 solutions. We need to solve the equation on the right. What do you get when add 10 to -26 on this|dw:1435069483961:dw|
put 18 where the x is @peachpi
2(18) - 10 = 26. That works for one answer. The absolute value equation has 2 solutions. 18 is the solution for 26. We need to find the solution for -26.
If you notice all your options have 2 numbers. Do you see what I'm saying?
@peachpi i multiplied 2 with 18 and subtracted 10 and got 26
yes that's right
that's the 18 we found above
do you understand how absolute value works?
@peachpi so whats the answer 18 and what
That's what we're solving this for. What do you get if you add 10 to -26? |dw:1435070054490:dw|
now divide by 2|dw:1435070238546:dw|
so your answers are 18 and -8
ok thank you @peachpi
